I personally have not done this many commits to curl in a single month (August 2019) for over three years. This increased activity is of course primarily due to the merge of and work with the HTTP/3 code. And yet, that is still only in its infancy…

Google has rolled out Chrome 77 into their stable channel as the newest version of their lightning fast web browser for Linux.

Chrome 77 now supports any HTML element providing form data via the "formdata" event, various security improvements, a Serial API for interacting with devices connected to physical or virtual serial ports, WebVR 1.1 support, tab sharing between devices, and a variety of other improvements.

Google has promoted the Chrome 77 web browser to the stable channel for all supported platforms, including Linux, Android, Windows, and Mac.
Google Chrome 77 introduces several performance enhancements to speed up your browsing experience, including new performance metrics that helps web developers measure how fast the content of a web page loads so you can access it faster than ever, as well as new form capabilities to support custom form controls.

"It has not always been easy for developers to measure how quickly the main content of a web page loads and is visible to users. The usefulness of existing metrics varies. Some metrics are only measurable in a lab, while others tell nothing about content that users care about. Consider the example below, taken from a DevTools performance audit," said Google.

Additionally, Google Chrome 77 introduces new origin trials that lets you to try new Chrome features before they are released and give feedback to the web standards community on their usability, effectiveness, and practicality. Users will be able to register for the origin trials here.

Google has announced that they would soon be performing a trial of utilizing DNS-over-HTTPS (DoH) in the Google Chrome browser. This experiment will be conducted in Chrome 78 and will attempt to upgrade a user's DNS server to a corresponding DoH server, and if available, use that for DNS resolution.

For those unfamiliar with DoH, it allows DNS resolution to be conducted over encrypted HTTPS connections rather than through the normal plain text DNS lookups.

The modern web is all about dynamic content. But in most cases, this is a technological illusion. A large number of website uses dynamically generated pages, i.e. stuff gets read from a database and rendered on the screen when requested, even for things that don't necessarily require any interaction. This takes resources, and might even be considered less secure, because bad or malformed instructions could theoretically generate something undesired.

The old Web was all about static content - HTML pages with links and images and not much else. Not bad, very light on the resources, and as secure as the Web server what does it. But then, not much interaction happens, and updating content can be tedious. What if there was something midway between the two worlds? That would be Nikola, a static site generator.

FPR16 got delayed because I really tried very hard to make some progress on our two biggest JavaScript deficiencies, the infamous issues 521 (async and await) and 533 (this is undefined). Unfortunately, not only did I make little progress on either, but the speculative fix I tried for issue 533 turned out to be the patch that unsettled the optimized build and had to be backed out. There is some partial work on issue 521, though, including a fully working parser patch. The problem is plumbing this into the browser runtime which is ripe for all kinds of regressions and is not currently implemented (instead, for compatibility, async functions get turned into a bytecode of null throw null return, essentially making any call to an async function throw an exception because it wouldn't have worked in the first place).

This wouldn't seem very useful except that effectively what the whole shebang does is convert a compile-time error into a runtime warning, such that other functions that previously might not have been able to load because of the error can now be parsed and hopefully run. With luck this should improve the functionality of sites using these functions even if everything still doesn't fully work, as a down payment hopefully on a future implementation. It may not be technically possible but it's a start.

Elementary OS – a Linux distribution (distro) built on top of the large, company-backed giant Ubuntu – is a mom-and-pop store by comparison.

But it's also one that's managed to capture the attention of even some seasoned Linux users thanks to its focus on user interface (UI) and even user experience (UX) – something often lacking from the more spartan distros.

With their focus on icon and UI themes sometimes suspiciously reminiscent of Apple's interfaces – the Elementary OS team have also earned themselves something of a label of “hipsters” in the community.

Hence, their decision some years ago to communicate news about the project by hosting their blog on another largely “hipster” online venue – Medium – was little surprise.

What's somewhat surprising is the about-face that the project is now making in leaving Medium for the sake of building their own blog hosted on GitHub Pages – using the static generator Jekyll.

We’re happy to be back in the saddle after the summer break! We want Vivaldi to be the perfect tool for you to control and enjoy the digital aspect of your lives.

And that’s why we are working on the things that count – the things that make you more productive and organised on the Web.

The new update has little gems that will give you a better control of sound behavior in Vivaldi. In addition, you have new options to access user profiles quicker, an enhanced status bar as well as overall improvements and security related fixes.

Web browsers are vital if you're going to have any sort of online experience on your computer. There are hundreds of choices out there, as well as the standard browser which will come pre-installed on your computer, but that's often not the best choice, and it can be quite an intimidating task to sift through every dodgy review site on the internet to try and find the right browser for you. Ending up with a Downloads folder filled with installers and a desktop littered with icons isn't what you want or need, so this collection of web browsers for Ubuntu should be able to help you decide on which one you want before you go and download every single browser available on the internet.

In the last few years, blogging has become a popular way of sharing one’s thoughts about almost anything. While people use blogs to express themselves, businesses go with blogging to cement their position as a competent authority in their area of operations. Over the past years, many have taken on blogging as various blogging software makes it as simple and straightforward as possible. Now, you can create a blog site even if you lack technical skills such as coding and web development.

Today, blogging software is being created for every operating system, not just for Windows and Mac. Since bloggers who want to make themselves heard are using different operating systems, it is essential to help you identify the best blogging software for Linux as well. Here are the top four blogging software for Linux.

In the afternoon of August 5 2019, I successfully made curl request a document over HTTP/3, retrieve it and then exit cleanly again.

(It got a 404 response code, two HTTP headers and 10 bytes of content so the actual response was certainly less thrilling to me than the fact that it actually delivered that response over HTTP version 3 over QUIC.)

The components necessary for this to work, if you want to play along at home, are reasonably up-to-date git clones of curl itself and the HTTP/3 library called quiche (and of course quiche’s dependencies too, like boringssl), then apply pull-request 4193 (build everything accordingly) and run a command line like:

curl --http3-direct https://quic.tech:8443

The host name used here (“quic.tech”) is a server run by friends at Cloudflare and it is there for testing and interop purposes and at the time of this test it ran QUIC draft-22 and HTTP/3.

An Easy Fix for a Stupid Mistake

I waited a long time for Mageia 7 and for OpenMandriva Lx 4. When both distros arrived, I was very happy.
But new distros bring changes, and sometimes it is not easy to adapt. Mageia 7 has been rock-solid: it is doing a great job in my laptop and both in my daughter's desktop and in mine. There is one thing, though. I have been avoiding a strange mesa update that wants to remove Steam.
OpenMandriva is also fantastic, but this new release provided options like rock, release, and rolling. When I first installed the distro, I chose rock because I was shying away from the rolling flavor. Eventually, I had to move to rolling because that was the only way in which I could manage to install Steam in both my laptop and desktop machines.

Intel's speedy Clear Linux distribution could be running under the hood of your car.
While we're fascinated by the performance of Intel's open-source Clear Linux distribution that it offers meaningful performance advantages over other distributions while still focused on security and offering a diverse package set, we often see it asked... who uses Clear Linux? Some argue that Clear Linux is just a toy or technology demo, but it's actually more.

Radeon ROCm 2.7.2 is now available as the newest update to AMD's open-source GPU compute stack for Linux systems.
ROCm 2.7.2 is a small release that just fixes the upgrade path when moving from older ROCm releases, v2.7.2 should now be running correctly. This release comes after the recent ROCm 2.7.1 point release that had corrected some components from properly loading the ROC tracer library.

There's an exciting patch set to GNOME Shell and Mutter now pending for finally wiring up the full-screen unredirected display / full-screen bypass compositing for helping the performance of full-screen games in particular on Wayland.
GNOME on X11 has long supported the full-screen compositing bypass so the window manager / compositor gets out of the way when running full-screen games/applications. That support under Wayland hasn't been in place and thus there is a performance hit for full-screen Wayland-native software. But now thanks to Red Hat's Jonas Ådahl, that infrastructure now appears to be ready.

After almost three years of research, planning and development we're proud to present the first public version of Xabber Server. Server is licensed under GNU AGPL v3 license, source code is available on GitHub. It is a fork of superb open source source XMPP server ejabberd by ProcessOne, with many custom protocol improvements an an all-new management panel.

After a summer hiatus during which I only released new packages for KDE Frameworks because they addressed a serious security hole, I am now back in business and just released KDE-5_19.09 for Slackware-current.
The packages for KDE-5_19.09 are available for download from my ‘ktown‘ repository. As always, these packages are meant to be installed on a full installation of Slackware-current which has had its KDE4 removed first. These packages will not work on Slackware 14.2. On my laptop with slackware64-current, this new release of Plasma5 runs smooth.

Later, the County official discovered that the two men were in fact, hired by the state court administration to try to "access" court records through "various means" to find out potential security vulnerabilities of the electronic court records.

The state court administration acknowledged that the two men had been hired, but said they were not supposed to physically break into the courthouse.

On the road to change, you’ll encounter fear and loathing. People will undoubtedly cling to old ways of working. Successfully making it to the other side will require commitment, passionate change agents, and unwavering leadership. You might wonder – is it really worth it?
Leaders who have made the switch to agile project management say that it has delivered benefits both large and small to their organizations, from the rituals that bring their team together – like daily stand-ups – to the results that make their business stronger – like better end products and happier customers.

Borislav Petkov has taken to improve the Linux kernel's memset function with it being an area previously criticzed by Linus Torvalds and other prominent developers.
Petkov this week published his initial patch for better optimizing the memset function that is used for filling memory with a constant byte.

In addition to the work being led by DigitalOcean on core scheduling to make Hyper Threading safer in light of security vulnerabilities, IBM and Oracle engineers continue working on Kernel Address Space Isolation to help prevent data leaks during attacks.
Complementing the "Core Scheduling" work, Kernel Address Space Isolation was also talked about at this week's Linux Plumbers Conference in Lisbon, Portugal. The address space isolation work for the kernel was RFC'ed a few months ago as a feature to prevent leaking sensitive data during attacks like L1 Terminal Fault and MDS. The focus on this Kernel ASI is for pairing with hypervisors like KVM as well as being a generic address space isolation framework.

While Intel CPUs aren't shipping with 5-level paging support, they are expected to be soon and distribution kernels are preparing to enable the kernel's functionality for this feature to extend the addressable memory supported. With that, the mainline kernel is also looking at flipping on 5-level paging by default for its default kernel configuration.
Intel's Linux developers have been working for several years on the 5-level paging support for increasing the virtual/physical address space for supporting large servers with vast amounts of RAM. The 5-level paging increases the virtual address space from 256 TiB to 128 PiB and the physical address space from 64 TiB to 4 PiB. Intel's 5-level paging works by extending the size of virtual addresses to 57 bits from 48 bits.

Using open source software is commonplace, with only a minority of companies preferring a proprietary-first software policy. Proponents of free and open source software (FOSS) have moved to the next phases of open source adoption, widening FOSS usage within the enterprise as well as gaining the “digital transformation” benefits associated with open source and cloud native best practices.
Companies, as well as FOSS advocates, are determining the best ways to promote these business goals, while at the same time keeping alive the spirit and ethos of the non-commercial communities that have embodied the open source movement for years.

Releasing Slax 9.11.0

New school year has started again and next version of Slax is here too :) this time it is 9.11.0. This release includes all bug fixes and security updates from Debian 9.11 (code name Jessie), and adds a boot parameter to disable console blanking (console blanking is disabled by default).
You can get the newest version at the project's home page, there are options to purchase Slax on DVD or USB device, as well as links for free download.
Surprisingly for me we skipped 9.10, I am not sure why :)
I also experimented with the newly released series of Debian 10 (code name Buster) and noticed several differences which need addressing, so Slax based on Debian 10 is in progress, but not ready yet. Considering my current workload and other circumstances, it will take some more time to get it ready, few weeks at least.
